Quick Answer
Mild altitude sickness symptoms include headaches, fatigue, nausea, and shortness of breath, which typically resolve within 24-48 hours as the body acclimatizes. Severe altitude sickness symptoms, however, include severe headaches, difficulty breathing, confusion, and loss of consciousness, and require immediate medical attention.
Understanding Altitude Sickness Severity
Mild altitude sickness is often referred to as Acute Mountain Sickness (AMS). It is a common condition that affects travelers ascending to high-altitude areas. To determine if symptoms are mild or severe, assess the individual’s condition, taking note of the duration and intensity of symptoms. Mild AMS typically resolves on its own within 24-48 hours.
Recognizing Severe Altitude Sickness Symptoms
Severe altitude sickness, also known as High-Altitude Pulmonary Edema (HAPE) or High-Altitude Cerebral Edema (HACE), is a life-threatening condition. Symptoms include severe headaches, difficulty breathing, and confusion. In cases of HAPE, the individual may experience a cough, chest tightness, and a decrease in oxygen saturation. HACE symptoms include severe headaches, confusion, difficulty walking, and loss of coordination. If these symptoms appear, seek immediate medical attention by descent to a lower altitude.
Acclimatization Strategies
To prevent severe altitude sickness, follow a gradual ascent plan. Aim to ascend no more than 1,000 feet (300 meters) per day. Take rest days as needed to allow the body to acclimatize. If symptoms of mild AMS are present, consider a 24- to 48-hour delay in ascent. Additionally, maintain proper hydration, as dehydration can exacerbate altitude sickness symptoms. Monitor oxygen saturation levels, and take necessary precautions in areas with extreme altitude variations.
